Find the equation of the regression line for the given data. Then use this equation to make the indicated estimate. Round decimals in the regression equation to three decimal places. Round estimates to the same accuracy as the given data.

The weight (in lb) and the highway fuel efficiency [in miles per gallon (mpg)] are shown for eight different cars in the table below. Find the equation of the regression line, and then estimate the highway mpg of a car that weighs 3500 lb.
